Article group is matched to multiple logos...

 
 
Error:
Article group is matched to multiple logos. Therefore, importing the logo is not possible.
 
Explanation:
Within an article group (articles with the same Article name, Specification header, Specification footer, Brand and Kind (i.e.: Article Group ID) only 1 logo can occur. An article with a different logo belongs to a different group.
Article groups with different logos do not allow import.
 
Solution:
Make sure that a unique logo is linked for each group. If it is true that the articles have different logos, the article group should be split up.
